Abstract
Abstract An apparatus and method for removing a measured portion of insulation from the end of a miniature solid-jacketed, coaxial cable, the apparatus including a spray chamber having an orifice containing a hermetic seal assembly for the insertion and support of the end of the cable, a precisely adjustable stop member for determining the length of cable to be inserted into the chamber, a spray assembly for applying etchant to the inserted portion, a switch in the face of the stop member for automatically actuating the spray assembly upon insertion of the proper length of the cable into the chamber and an adjustable timing mechanism for controlling the amount of etchant applied to remove the metal sheath. The exposed dielectric insulation is thermally removed, and the conductor cleaned and trimmed to the desired length.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
60 words
An apparatus for removing a selected length of the outer metal jacket of solid-jacketed type cable comprising: a chemical etchant spray chamber; orifice means for sealably inserting an end of said cable into said spray chamber; and adjustable means mounted in a wall of said spray chamber for predetermining the length of said cable to be inserted into said chamber.
Claim 2
Independent Claim
60 words
An apparatus for removing a selected length of the outer metal jacket of solid-jacketed type cable comprising: a chemical etchant spray chamber; orifice means for sealably inserting an end of said cable into said spray chamber; and adjustable means mounted in a wall of said spray chamber for predetermining the length of said cable to be inserted into said chamber.
Claim 3
Dependent Claim
38 words
The apparatus of claim 1 whErein said adjustable means is mounted in a wall of said spray chamber opposite said orifice means and wherein said adjustable means includes a rod extending outside said chamber and threadably engaged therewith.
Claim 4
Dependent Claim
28 words
The apparatus of claim 2 including calibration on the portion of said rod extending outside said chamber for measuring the predetermined length of the jacket to be removed.
Claim 5
Dependent Claim
33 words
The apparatus of claim 2 wherein said orifice means has a longitudinal axis for positioning and supporting said cable and wherein said longitudinal axis is aligned with the longitudinal axis of said rod.
Claim 6
Dependent Claim
17 words

Claim 9
Dependent Claim
37 words
The apparatus of claim 1 wherein said spray chamber includes: means for urging a flow of said etchant spray against said inserted predetermined length of said cable; and means for regulating the duration of said urging means.
Claim 10
Dependent Claim
27 words
The apparatus of claim 3 wherein said adjustable means include: means responsive to the insertion of said selected length of said cable for actuating said urging means.
